分别经肝动脉和门静脉注射５１Ｃｒ－蛙红细胞及１２５Ｉ－碘化油，测定其在大鼠肝癌和肝组织中的放射性分布，证实了肝癌主要由肝动脉供血．门静脉在肝癌周边部位参与血供。肝动脉栓塞后肝癌内门静脉血供增加，肿瘤周边部位可见碘化油残留。
Hepatic artery and portal vein were injected with 51Cr-frog erythrocytes and 125I-iodinated oil, respectively, and their radioactivity distribution in rat liver and liver tissues was determined. It was confirmed that hepatic artery was mainly supplied by hepatic artery. The portal vein participates in blood supply in the peripheral part of liver cancer. After hepatic artery embolization, the portal venous blood supply in hepatocellular carcinoma increased, and iodized oil remained in the peripheral part of the tumor.
